I have tried those garbage Itrips and even an expensive pioneer unit in my girls Escalade but I hate the sound quality. What have u guys done so u can listen to your Ipod/Iphone in your 99/01 Cobras?
Peripheral Electronics makes an interface that charges the Ipod and lets you control it through the Mach 460 HU.

I am pretty sure if you but the universal aux jack and the PXDX harness/adapter thing it should just plug right into the back of the headunit then you can plug your mp3 player into it.
edit:
nvr mind the generic aux adapter wont work with 6 disc changers, aka mach 460
